1
All static performance tests (except I
OUT
) are performed in a closed-loop system using an external precision OP177 I-to-V converter amplifier. The AD5554 R
FB
terminal is
tied to the amplifier output. Typical values represent average readings measured at 25°C.

All input control signals are specified with t
R
= t
F
= 2.5 ns (10% to 90% of 3 V) and timed from a voltage level of 1.5 V.
